ACKNOWLEDGMENTS 



This publication was made possible largely by the generous support of the U.S. Naval 

 Oceanographic Office (Contract N62306-67-C-0318), through the Scripps Institution of 

 Oceanography (Carl L. Hubbs, Principal Investigator) during the most intensive part of the 

 investigations (1968). I am most grateful for that support. In particular, I wish to thank 

 Bernard J. Zahuranec and G. Brooke Farquhar, of the Division of Acoustical Oceanography of 

 that Office, for instigating both the study and the initial funding. Particular thanks are also 

 due to the National Science Foundation for support through grants to Carl L. Hubbs during 

 the early and final stages of the work. 



The following also deserve special thanks. John C. Marr and Richard Shomura, formerly 

 of the National Marine Fisheries Biological Laboratory, Honolulu, gave permission to 

 examine a large series of collections from the central Pacific area. Thomas A. Clarke, Univer- 

 sity of Hawaii, provided specimens and unpublished data on vertical distributions of some 

 species from Hawaiian waters; he and his co-workers offered valuable criticism of some keys to 

 identification. C. Karrer, Zoologisches Museum, Berlin, provided type material of Diaphus 

 fulgens. G. E. Maul, Museo Municipal do Funchal, Madeira, and Jorgen Nielsen, Univer- 

 sitetets Zoologiske Museum, Copenhagen, have kindly lent specimens from the Atlantic Ocean 

 for comparative studies. 



Dr. Nielsen made available a large unstudied collection of lanternfishes made by several 

 Danish expeditions, principally the Galathea. Dr. P. A. Hulley, South African Museum, Cape 

 Town, kindly permitted me to retain for study a large collection of lanternfishes taken in 

 waters surrounding the tip of South Africa. The latter specimens and those of the Danish 

 expeditions have been of great value as comparative material. 



I also wish to thank Drs. E. H. Ahlstrom and G. H. Moser, and their coworkers at the 

 National Marine Fisheries Service, Southwest Fisheries Center, La Jolla, California, for 

 specimens, many discussions, and much testing of the various keys to identification. Michael 

 Barnett has also tested many of the keys during preparation of his doctoral dissertation; his 

 criticisms and suggestions are greatly appreciated. 



Bernard J. Zahuranec contributed generously of his time and effort in guiding the manu- 

 script through the technical details of Government publication. I am grateful to Betty N. Shor 

 for her very considerable efforts in typing the original manuscript. Charmion B. McMillan 

 typed and gave valuable help In proofreading the final manuscript. Carl L. Hubbs kindly gave 

 advice on nomenclature. 



Lastly, I am most grateful to the late Rolf L. Bolin, who, upon his retirement from active 

 ichthyological work, very kindly presented to me his valuable files of notes and illustrations of 

 type specimens, and of microfilms of old and difficult-to-obtain literature, compiled during his 

 studies of type material of myctophid fishes in the various museums of the world. I have 

 presented these to Dr. Basil G. Nafpaktitis, University of Southern California, Los Angeles.
